STRUCTURAL-KINEMATIC INTERPRETATION OF SMALL-AMPLITUDE TECTONIC DEFORMATIONS SPREAD WITHIN SABURTALO SYNCLINE AND LISI ANTICLINE

Introduction

Structural-kinematic interpretation of small-amplitude tectonic deformations spread within saburtalo syncline and lisi anticline. Interpret structural-kinematic tectonic deformations in Saburtalo syncline & Lisi anticline. Study small faults, horizontal compression, and Tbilisi deep fault's dynamic influence.

Abstract

Of the existing deformation structures identified by us within the Saburtalo syncline and Lisi anticline, small faults of latitudinal and meridional strike prevail, which by their kinematics correspond to upcast and downcast faults. Several gentle faults are noted across  the pitch of layers, which then pass into folded deformations. All these deformations point to the leading role of north-directed vectors of horizontal compression and at the same time, since their intensity increases to the east, it is thought to be caused by the dynamic influence of the Tbilisi meridional deep fault on a certain area.

Review

This study presents a structural-kinematic analysis of small-amplitude tectonic deformations within the Saburtalo syncline and Lisi anticline, identifying prevalent small faults with both latitudinal and meridional strikes, interpreted kinematically as upcast and downcast structures. A key observation is the presence of gentle faults that transition into folded deformations across the layer pitch. The authors propose that these deformation patterns primarily reflect north-directed horizontal compression, with an observed eastward increase in deformation intensity attributed to the dynamic influence of the Tbilisi meridional deep fault. The paper appears to offer a detailed, localized investigation that promises to enrich the understanding of the regional tectonic architecture. The focus on identifying specific deformation structures and interpreting their kinematics, coupled with the intriguing observation of a fault-to-fold transition, suggests thorough fieldwork and analysis. The proposed connection between regional north-directed compression and the localized dynamic influence of a major deep fault provides a compelling interpretative framework, which could be a significant contribution to understanding the neotectonics of the area. While the abstract effectively outlines the study's core findings and hypotheses, it could benefit from additional information regarding the methodology employed. Details concerning the scale of "small-amplitude" deformations, the specific techniques used for kinematic analysis, and how deformation intensity was quantified would enhance the robustness of the interpretations. Furthermore, clarification on the evidence or modeling supporting the "dynamic influence" of the Tbilisi deep fault, beyond correlation, would strengthen this central claim. Providing a brief context within existing regional geological literature would also help readers assess the novelty and significance of the presented interpretations.
